Would there be any further improvement possible on ADSL2 (G.992.3)?
Are there any potential downsides?

Do all the tones with no bits allocated to them really cause that much trouble? On a long line, there probably won't be any bits allocated to any of the highest frequency tones in the ADSL1 range.

Up until now, the response I've received from Plusnet staff on the forum has always been to state that the policy was not to move customers with long lines onto ADSL2+ due to instability issues, but no mention of ADSL2.
Router is currently configured to automatically connect using the detected modulation (if that's the correct terminology). Do I need to change it to ADSL2 only to ensure it doesn't attempt to connect using ADSL2+? I would like to avoid this possibility as it could appear as an unstable line so that target noise margin is increased

The one thing is that with ADSL1 you are stuck with a 6dB minimum noise margin whereas on ADSL2 I believe it can drop to 3dB with an improvement in speed. My line just won't stand that but some may and the only way mine would improve is replacement of the main inter connectors from the exchange to the primary cab and possibly from the primary cab to the secondary cab (not many people have those but it is because of the dispersed properties in my area)

I would, at least, start by "forcing" ADSL2 as you suggest and see how it goes. It may be beneficial to log the bit loading information (on the 585v7 it is the telnet command "xdsl debug bitloadinginfo" ) whilst using ADSL1, then with ADSL2. It will probably stop well before tone 256, tailing off from about 150 (max is 15 bits) - so the additional ADSL2+ tones would have no beneficial effect.

ITU-T G.992.1 is ADSL1
ITU-T G.992.3 is ADSL2
ITU-T G.992.5 is ADSL2+

Quote from: Oldjim It should go to ADSL2 automatically
Yes ... and no It's some time since I selected ADSL2 instead of Auto, but ISTR that every now and again it would switch to ADSL2+ for a couple of hours and then fall back to ADSL2, dropping the sync speed. A couple of those and you are down from a reasonably stable
Edit: just spotted a trypo

@Oldjim - allowing the router to autoselect would be the most convenient, I didn't know if Plusnet could change my connection to ADSL2 specifically.
@PeeGee
I haven't a clue how to do this. I have the Plusnet supplied TG582n router.
